LIKE sunshine on a cloudy day, the bright yellow blooms of Lysichiton americanus are a cheering sight on a dank, late April afternoon in Brodick Castle’s woodland garden. But it’s their scent that hits you first: heady, powerful, it’s actually rather revolting, unless you are a creepy-crawly on the hunt for a bit of rotting flesh. For when these flowers emerge on the frozen reaches of their native north-western America and Canada – having used their own heat-generating capacity to melt through snow – that fetid, sulphurous odour attracts the carrion-loving beetles and flies that are the only available pollinators at this time of year. . http://www.heraldscotland.com/news/16207827.Warzone_in_our_garden__how_Scotland_is_fighting_back_against_invasive_species/?ref=rss
